Should I oil the barrel of my ptr 91 gi?
A newbie question - should I oil the barrel of the ptr 91 gi? I usually put a couple drops of m-pro 7 gun oil down the barrel (after cleaning with gun cleaner), then push through an oiled cleaning patch, and then a dry patch.

These are my first guns and my knowledge is very limited, so go easy on me
